In this paper, we consider the optimal dividend problem for the compound Poisson risk model. We assume that dividends are paid to the shareholders according to an admissible strategy with dividend rate bounded by a constant. Our objective is to find a dividend policy so as to maximize the...

This paper studies some asymptotic results for both finite and ultimate ruin probabilities in a discrete time risk model with nonconstant interest rates, under the assumptions that the individual net losses are bivariate upper-tail independent, identically distributed random variables having a...

In this paper, we consider the dividend payments in a compound Poisson risk model with credit and debit interests under absolute ruin. We first obtain the integro-differential equations satisfied by the moment generating function and moments of the discounted aggregate dividend payments....

Let Xt be a standard d-dimensional Brownian motion with drift c started at a fixed X0, and let T be the hitting time for a sphere or concentric spherical shell. By using an appropriate martingale, a Laplace-Gegenbauer transform of the joint distribution of T and XT is determined.

We consider a one-dimensional time-homogeneous regular diffusion between two constant elastic barriers as well as the special cases with pure absorbing and/or reflecting barriers. We derive the recurrence relations for moments of the first passage time. As examples, we consider several popular...
